To all whom it may concern:

Be it known that I, 'JoHN F. OGoNNoR, a citizen of the United States, residin at the city of Chicago, in the county of 00k and State of Illinois, have invented a certain new and useful I-m rovement in Side Bearings for Railway-Cars, of which the following is a full, clear, concise, and exact descriptionyreference being had to the accompanying drawings, forming a part of this specification.

My invention relates to improvements inside bearings for railway cars.

The object of my invention is to provide an adjustable side bearing of simple c0n struction and efiicient operation.

- In the drawings forming a part of'this specification, Figure 1 is an end view of my improved side bearing mounted between a truck and body-bolster of a railway car,only a portion of the bolsters being shown in the drawing. Fig. 2 is an enlarged plan. view of the bearing. Fig. '3 is an enlarged longitudinal vertical section taken on line 33 of Fig. 1 Fig. 4 is'a cross section taken on line 44! of Fig. 3. Fig. 5 is a plan view of a modification.

Referring to the. drawings, the numeral 6 indicates a body-bolster of a railway car, substantially one-half of the bolster being shown in the drawing, the said bolster having mounted thereon a bearing plate 7. My improved side bearing 8 is provided with a base member 9 which has flanges 10 appropriately perforated as at'11 for the passage of rivets 12 or their securing means which engage it to the truck-bolster 13, only a portion of which is shown in the drawing. The base member 9 is provided intermediate its ends with an upstanding post 14 provided with a rounded end 15 which in preferable construction presents a convex surface 16in longitudina section,.as shown in Fig. 3, and a similarconvex surface 17 in cross section, as shown in Fig. 4. A cradle 18 is provided intermediate its ends with a concaved bearing member 19 which is mounted upon thewrounded end 15 of the. post 14 and 's provided with the pertoration 20 regisierlng with a perforation 21 in the ost 14 for the passage of the retaining b t 22. The said bolt has a head Specification of Letters Patent.

23 which is countersunk in the bearing.

member as at 24, and anut 25 which is countersunk in the base member as at 26.

The perforations 20in the bearing member and 21 in the post are of a diameter sufli-" ciently larger than the diameter, of the bolt to permit the oscillation of the" cradle. upon the post in both longitudinal and transverse directions. The cradle 18 is provided at either side of the bearing member 19 with the vertical roller-receiving recesses 2727,

in each of which is mounted a roller 28, g

at one end with a perforation 31 for the passage of a cotter 32, and at their other ends are joined by the integral member 33 which with a pair V of axles forms a U- shaped roller supporting bolt which in its entirety I designate by the numeral 34.

In Fig. 5 a modification is illustrated, the base member being indicated at the numeral 40 and having suitable flanges 41 for the passage of the rivets 42 to secure it to the bolster. The base member is rovided with the center post 43 upon w ich the cradle 44 is adapted to oscillate in either direction. It is provided with the retaining bolt 45 which passes through the cradle The andsecures it tothe base member. cradle also is provided with the roll-receiving chambers 4646, in each of which is mounted a roller 47, the rollers being supported upon the axle portions 48 of the U- shaped bolt 49. The structure of the modification illustrated in Fig, 5 is the same as that illustrated in Figs. 1 to 4 inclusive of the drawing, with the exception that the axle ortions of the U-shaped bolt 49 are radia from a point upon the bolster, its, for instance, where the king pin asses through the bolster and the rollers 4 and the openings in the cradle to receive them are similarly radial.

plate. The double pin for supporting the rollers or U-shaped axle serves to prevent the axle portions thereof from rotating with the rollers, and consequently wear between the axle and the metal of the cradle surrounding the perforations 5l-5l therein,

through which the axles pass, is prevented.

I claim': 1. In a side bearing for railway cars, the combination with abase casting adapted to be secured to a bolster, said base casting being provided with an upstanding post, of a cradle supported on said post, said cradle and post having a universal bearing therebetween, and a roller-carried by said cradle.

2. In aside bearing for railway cars, the combination with a base member adapted to be secured to a bolster, said base member having a vertically extending post, of a cradle supported on saidpost, the cradle and post providing a universal jointtherebetween, and a pair of rollers carried by said cradle, said rollers being located on opposite sides of said post.

3. In a side bearing forrailway cars, a base member, a cradle, and rollers mounted in said cradle, the base member being provided With a post, the cradle member having a bearing member engaging said post, the cradle being provided with means securing it to thebase member, the said means permitting both longitudinal and transverse gscillation of the cradle upon the base mem- 4. In a side bearing for railway cars, a base member, a cradle, and rollers mounted in the cradle, the cradle being provided with a bearing member, and the base member being provlded with a post engaging the same, the post being transversely and longitudinally rounded to permit both the longitudinal and transverse oscillation of the cradle thereon.

5. In a side bearing for railway cars, a base member having an upstanding post with a rounded upper end, a cradle provided on its underside with a curved bearing fitting said rounded upper end of the post, a roller carried by said cradle, and a bolt extending vertically through said 0st and the cradle for retaining the latter 1n operative position.
